Hyderabad Police Commissioner M Mahender Reddy said that 30-year-old Munawad Salman, a former Google employee, was picked up on Tuesday. He has been let off after questioning, Reddy told reporters.

Hailing from Tamil Nadu, Salman got allegedly attracted to Islamic State of Iraq and Syria (ISIS) through social media networks and had planned to join the jihadist group, according to a senior police officer.

Salman, who had worked at the Hyderabad office of technology giant Google before quitting his job around seven months ago, was detained following inputs that he was making efforts to procure a visa to Saudi Arabia from where he allegedly planned to flee to Iraq, the officer said.

He was reportedly studying posts of the ISIS and their propaganda on internet and social media platforms for past six months and had planned to join the group's fighters in Iraq.

"After he was picked up, Salman was was bound over also. We have counselled him through his parents and his brother to keep good behaviour. He was asked to keep away from indulging in those activities. Now he has been let off. We have not registered any case," a senior intelligence officer said.

"He has been asked to desist from such things, and if he is found indulging in such activities again, a specific case will be booked and he will be arrested," he said.

"After quitting his work at Google, he is jobless. He was planning to go out of the country and trying for visa. He is from Tamil Nadu and for job purpose he came to Hyderabad," the officer said.

Reacting to queries on the matter, Reddy said that the police was keeping a watch on the techie's activities since four Hyderabadi youth were caught while they were allegedly trying to join the ISIS.

Salman was asked to appear before police and taken before the Revenue Divisional Officer (RDO) wherein he gave an undertaking for good conduct, Reddy said, adding that "he has been let off and is not in our custody."

The Hyderabad Police had in August "foiled" an alleged attempt by a group of four young men from the city, including two engineers, to join the rank of ISIS after they were tracked down to Kolkata from where they were allegedly preparing to flee to Iraq.

The youth, who were "attracted" towards the ISIS propaganda on social networking sites and net-based mobile messenger, were questioned and let off after counselling.

The Hyderabad Police had on October 22 arrested a suspected SIMI operative and an aide of Indian Mujahideen media in-charge (both youth from Maharashtra) from Secunderabad. They were allegedly planning to go to Afghanistan to get training from militant organisation Al Qaeda for carrying out terror activities in India, police had earlier said.
